Improvement in washing-machines



UNITED STATES PATENT OFFICE.

WM. M. DOTY, E P. DOTY, AND ELLIS DOTY, OF JANESVILLE, WISCONSIN.

IMPROVEM ENT IN WASHING-MACHINES.

Specification forming part of Letters Patent N0. 56,910, dated August 7,1866.

To all lwhom it may concern:

Beit known that we, WILLIAM M. DOTY, E. P. Do'rY, and ELLIS Do'rY, ofJanesville, in the county pi' Rock and State of Wisconsin, have inventeda new and Improved Washing-Machine; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying Y drawings, forming part of thisspecification,

in which- Figure 1 represents a transverse vertical section of thisinvention, the line a: ac, Fig. 2, indicating the plane of section. Fig.2 is a plan or top view of the same.

Similar letters of reference indicate like parts.

This invention relates to certain improvements in that classofWashing-machines on which Letters Patent have been granted to us January30, 1866.

Our present improvements consist, first, in

.the use of a spring on each of the fulcrumpins of the oscillating`Wash-board, with its ends extending from said fulcrurn-pins in oppositedirections, one to bear on the edge of the tub and the other under a pinprojecting from the lo aoket which forms the bearing for theappropriatefulcrum-pins, in such a manner that in depressing the handleeach spring is -Wound up and the pressure on each fulcrum-pin isbalanced, one end of the spring pressing up and the other down, and saidpins are prevented from wearing out.

It consists, further, in combining with the Wash-board flanged segmentalcheek-pieces,

` which are grooved to receive the handle, and

so formed that they prevent the water from splashing out over the endsof the tub.

It consists, finally, in the arrangement of cleats on the ends of thetub, in combination with the upper ends of the' legs, which are -securedto the tub, each by screws or bolts, in

such a manner that the end pieces of the tub are free to expand and tocontract without being liable to crack, and at the same timeV the legsare firmly held in position.

' A represents a tub, made square or oblong, or in any other suitableform or shape, and

provided with brackets a, which rise fromV the edge of the tub, and theother, d, to catch under astop, e, which projects from the bracket a. Bythis arrangement the springs are wound up simultaneously from both ends,and the full power thereof is brought into use when the handle is set inmotion, and at the same time the lateral strain exerted onV thefulcrum-pin by one end of the spring is counteracted by that exerted bythe other end,

and the pins are prevented from wearing out.

By making the stops c adjustable the strain of the springs can beincreased or decreased at pleasure.

The cheek-pieces U are made Wide and caused to project a suicientdistance above the wash-board, and their ends are chamfered oft', sothat the water is prevented from splashing when the wash-board is set inmotion. These cheek-pieces are grooved to receive the handle D, and thishandle D is so arranged that it can be readily taken out and that thewhole machine can be packed up in a comparatively` small compass.

The tub is supported by four legs, E, Which are fastened toits ends byscrews or bolts, and the upper ends of said legs catch in suitablesockets in cleats F, which are secured to the ends of the tub, as shown.By this arrangement the legs are enabled to accommodate themselves tothe expansion and contraction of the end pieces, and they are firmlyheld in position Without causing said end pieces to crack, which theyare liable to do if the legs are fastened to both their lower and upperedges.

We disclaim everything included in our former patent of January 30,1866i.

What we claim as new, and desire to secure by Letters Patent, is-

l. The combination of the spiral springs c d fulcrum-pins b, andoscillating Wash-board B, constructed as described, and operatingsubstantially as and for the purpose specied.

2. In combination With the above, the projecting cheek-pieces C, Withchamfered edges, constructed and operating` substantially as an d forJche purpose described.

3. The cleats F, fastened to the ends of the tub, and provided withsockets to receive the upper ends of the legs E, which are fastened tothe lower edges ofthe ends of The tub with screws orbolts, substantiallyas sind for Lhe purpose set forth.
